　　import java.io.*;
public class Mine{
public static void main(String argv[]){
Mine m=new Mine();
    System.out.PRintln(m.amethod());
}
public int amethod(){
       try{
           FileInputStream dis =new FileInputStream("Hello.txt"); //1，抛出异常
       }catch ( Exception ex) {
               System.out.println("No sUCh file found");   //2.catch捕捉异常，并执行
               return -1;                                  //4,return 返回
       }finally{
               System.out.println("Doing finally"); //3.finally一定会执行，在return之前。
       }
        return 0;
    }
}

运行结果:

C:/java>java   Mine
No such file found
Doing finally
-1
